SLICING-MACHINE.

Specification of Letters Patent.

Application led September 28, 1906. Serial No. 336,630.

To all whom 'it may concern:

Be it known that I, FRANKLIN P. BURK- HARDT, a citizen of the United States, residing at Springield, in the county of Clark and State of Ohio, have invented certain `new and useful Improvements in Slicing- `Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to slicing machines, and more particularly to manually operated machines of the character ordinarily employed for slicing cured meats and similaisubstances.

The object of the invention is to provide a machine of this character in which the cutter will have a rotary cutting action, as well as a draw cut, and to provide such a machine which will be compact in construction so that it will occupy but little counter space and will be strong and durable.

' A further object is to provide a machine of this character which will have a positive feed actuated from the cutting mechanism.

With these objects in view my invention consists in the construction hereinafter to be described and then more particularly pointed out in the claims.

j In the-accompanying drawings, Figure 1 is a top plan view of a machine embodying my lnvention, with the cutter in its raised position; Fig. 2 is an end elevation of the same; Fig. 3 is a longitudinal sectional View, taken centrally through the support- "ing table and centrally through the cutter and its supporting arm; Fig. et is a detail sectional view, taken on the line m of Fig.

8 and looking in the direction of the arrows z-Fig. 5 is a detail view of the carriage; Fig. 6 is a sectional view, taken on the line y g/ of Fig. 1; Fig. 7 is a sectional view of a portion of the supporting base, showing the feed ratchet and its coperating mechanism with the cutter in elevated position; Fig. 8 is a similar view with the cutter in its lower position; Fig. 9 is a detail view of the feed ratchet; Fig. 10 is a j longitudinal sectional view of the same; and

Figall is a side elevation of a portion of the machine, showing the mechanism for operating the feed ratchet.

` In these drawings, I have illustrated one 4 embodiment of my machine, in which the rbase `or supporting table for the 4article to be Patented Sept. 20, 1910.

shell of cast metal orV similar material and provided at its corners with lugs or lips 2 for attaching the same to the counter or other supporting medium. One of these lips is enlarged to form a supporting base 3 `for the cutting mechanism. The supporting base comprises a flat base portion 4.- and an upwardly extending rib 5, to which is firmly secured, by means of bolts 6 or any suitable medium, a plate 7 provided with a base portion 8 and having apertured lugs 9 in which is secured a shaft 10, extending a short distance beyond the outer lug. Upon this shaft is mounted a bearing sleeve or collar 11, having rigidly secured thereto an arm or bracket 12 which is provided at its outer end with a handle 13 adjustably secured thereto. The outer end of this arm is provided with two bolt holeslt, arranged longitudinally of the arm, and the handle 13 is provided at its inner end with a bolt hole 15 adapted to register with the inner hole 14: of the arm and be secured thereto by a bolt 16. That portion of the handle adjacent to the outer hole 14 of the arm 12 is provided with a segment 17, having formed therein a series of holes 18 adapted to regis ter successively with the outer hole 14 of the arm 12, when the handle is moved around the pivot formed by the bolt 16 in j the inner bolt hole of the arm 12, thereby allowing the bolt 19 to be passed throuvh any one of the series of holes in the handIe, thus securing the handle to the arm in any desired position.

Intermediate the handle 13 and the bearing sleeve 11 the arm member 12 is provided with a bearing aperture 20, in which iS r0- tatably mounted a bearing sleeve 21, having at one end an annular flange 22 engaging the adjacent face of the bearing, and provided at the opposite end with a nut 23 for adjusting the same in said bearing, and a jam-nut 24 for locking said adjusting nut in position. A shaft 25 is mounted in said bearing sleeve and projects beyond the same at each end thereof. Upon that end of said shaft adjacent to the flange 22 is mounted a rotary disk cutter 26 which has its convex portion resting in the support formed by the flange 22, which is formed concave, as

shown at 27, to receive said disk. A' nut 28 engages the screw-threaded end of the shaft 25 and locks the cutter disk thereon. At

the opposite end of the bearing sleeve 21, and preferably immediately adjacent thereto, the shaft 25 has mounted thereon a pinion 29 which has at its outer end and rigidly secured thereto a clutch member 30 which is mounted in a recess 31, formed in the balance wheel 32 which is rigidly secured to the shaft 25 at a point beyond the pinion 29. The recess 31 is preferably formed by means of an annular flange 33, the inner walls of which form the second member of said clutch and coperate with the member 30 which is secured to the pinion 29. The clutch member 30 is preferably provided with a series of tapered recesses formed in the periphery thereof and adapted to receive the rollers 30a which operate to grip the members 31 when the member 30 is rotated in one direction and to release the same when the member 30 is rotated in the opposite direction. A segment 34 is mounted upon the end of the shaft 10 projecting beyond the outer bearing lug 9 and is rigidly secured thereon by means of a downwardly projecting` arm 35, having a set screw 36, adapted to engage the plate 7 of the supporting lugs 9. This segment is provided with a rack 37 which meshes with the teeth of the pinion 29 and rotates the same as the arm 12 is rotated about its pivotal axis 10. The clutch members 30 and 33 are preferably so arranged that as the cutter is moved to its elevated position, the pinion will revolve freely on the shaft 25, but as the cutter is moved forward into engagement with the substance to be sliced the clutch members lock, thereby rotating the balance wheel 32, the shaft 25 to which it is rigidly secured, and the cutter disk 26 which is secured to said shaft.

On the base or supporting table 1 is mounted a sliding carriage 38 which may be of any suitable construction and may be fed forward in any suitable manner, but I prefer to provide means whereby the carriage may be fed forward step by step as the cutter is operated, or may be fed continuously either when the cutter is idle or when the cutter is in operation. I have herein shown one form of carriage and feed mechanism which is adapted to accomplish this result. The carriage here shown is provided with upwardly extending slotted arms 39, between which is secured a cross bar 40 adapted to move vertically of said arms and to be secured thereto in its adjusted position by means of the bolts 41, which extend through the lugs 42 on the cross bar and through the vertical slots in the arm 39, and which are provided on their outer ends with thumb-nuts 43. The bar 40 is provided on its lower face with downwardly projecting teeth 44 which coperate with the teeth 45 o n the carriage 38 to secure the meat or substance to be cutfirmly in position thereon. The carriage is further provided with upwardly extending side portions 46, which coperate with the cross bar 40 and teeth 45 to retain the meatsecurely in position. A rib or projection 47, secured on thel under side of the carriage 38 and provided with a pin or lug 48, ext-ends through a slot 49 formed in the base or supporting plate 1 and extending longitudinally thereof, that is, in a direction transverse to the direction of movement of the cutter disk. rIfhis slot may be of any desired length, but in the o tus, and is provided with a crossbar 53 orother suitable means for manually rotating the same in the bearings 50. This shaft 51 is provided with a spirally arranged groove or thread 54 which may extend through all or a portion of its length, as may be desired, and is adapted to engage the lug or pin 48, mounted on the carriage 38, to move the same forward as the shaft is rotated in its bearing. On that end of thisjshaft 51 nearest the cutting apparatus is rigidly mounted a ratchet wheel 55, provided w-ith a suitable pawl for engaging the teeth thereof and preventing the same from moving in a reverse direction. This pawl may be of any suitable construction, that in the drawings being merely a strip of spring metal 56, secured to the base 1 and having its free end bent downward to engage the teeth of the ratchet 55. Loosely mounted on the shaft 51, and preferably immediately adjacent to the ratchet wheel 55, is a sleeve or collar 57 having an arm or projection 58 and provided with a pawl adapted to engage the teeth of the ratchet 55 and rotate the same and the yshaft to which it 'is' secured when the arm 58 and the collar 57 are oscillated on said shaft. This pawl may be of any suitable character, but I prefer that shown in the drawings, in which I provide the arm 58 with a projection or lug 59 extending beneath the ratchet wheel 55 `and having a recess 60 formed therein, in which is mounted a pawl 61, having. a beveled tooth 62 adapted to engage the teeth of the ratchet wheel 55. The lower end of the pawl 61 is provided with a shank or spindle 63 extending through an aperture ,64' in the bottom of the recess. The spring 65 is coiled about the spindle 63 and bears at one end against the shoulder 66 on thevpawl 61 and yat the other end against the base of the recess 60, thereby holdmo the pawl 61 normally in engagement with the teeth` of said ratchet wheel. A lug 67 is provided on one side .of said `pawl and extends through a slot 68 in the wall of the recess 60 to guide the pawl in its reciprocating movement and prevent the same from turning in the recess. An arm or lever 69 is pivot'ed at one end to the'` arm 58, and, passingthrough `a slot 70 in the frame 1, extends some distance beyond the same and has its outer end pivoted to 1an arm or link 71 which is rigidly mountedzon a rockshaft 72. The rockshaft 72 is `rotatably mounted in bearings 7 3, formed in lugs 74 mounted on the supporting bracket or base 4, and is provided with an arm 75 extending at substantially right angles thereto. This arm is preferably formed by bending the end of the rockshaft 72 at right angles to said shaft and providing the same with a flat upper surface 76 which is slightly curved longitudinally of said arm. The arm or bracket 12 is provided with a lug 77, in which is secured a finger or pin 78, arranged inthe same 4vertical plane with the arm 76, and having its end beveled or rounded to coperate therewith and adapted to engage the same when'the cutter approaches its elevated position.

i As the cutter is raised the arm 78 comes into engagement with the arm 75, depressi-ng'the same and rocking the shaft 72, thereby `transmitting through the link 71 a longitudinal movement to the arm 69, which, in turn, rocks the arm `58 about the shaft 51, causing the pawl 61, which is in engagement with the teeth of the ratchet wheel 55, to rotate said ratchet wheel and the shaft to which it is secured, thereby causing the wall ofthe spiral groove 54` on said shaft to engage the pin 48 on the carriage 38 and move the same forward a distance corresponding to the amount of rotation o f the ratchet g wheel 55. The amount of this rotation is regulated by the number of teeth over which the pawl 61 rides in its 'return movement. To regulate the number of teeth over which the `pawl rides, I provide a set screw 79,

` mounted in a lug 80, carried by the base 1 and adapted to engage the arm 69 as the same moves with th shaft 72 and limit the movement of the same about said shaft, thereby limiting the j return movement of the arm 58. A spring 81 is securedat one end to the arm 58 and at its opposite end to the base 1 and serves to return the arm 58 to its normal position when the arm` 75 of the rockshaft 72 has j been released. A guard 82 extends around theperiphery of the cutting disk and is mounted in brackets 88 which are secured to the arm 12. l

"The operation of the machine will be .readily understood from the foregoing dee link 71 on the rockp scription. In brief it is as follows: The material to be sliced 'is placed upon the carriage 38 and firmly secured in position by the adjustment of the bar on the arms 39 of said carriage. The carriage is then placed in position on the base 1 with the pin 48 in engagement with the spiral groove 42 and the shaft 51 rotated by hand through the medium of the cross bar 53 to quickly lbring the carriage, and the substance carried thereby, into position adjacent to the cutting tool. The cutter is then raised by means of the handle 13 to its uppermost position, and, as it approaches this position, the arm 78, carried by the bracket 12, comes into engagement with the arm 75 on the rockshaft 72 and depresses the same, thereby rocking the shaft 72 in the bearings 73 and imparting movement to the arm or lever 69 and the arm 58, thereby causing the pawl` 6l to engage the teeth of the ratchet wheel and rotate said ratchet wheel and its shaft to advance the carriage 38 the desired distance under the cutter 26. The cutter is then moved forward into engagement with the substance to be sliced, and, as it moves forward, the pinion 29 engages with the teeth of the rack 34 and is rotated, the clutch member engaging positively with the balance wheel 32 which is rigidly secured to the shaft, thereby rotating the shaft and the cutter as the same move forwardly and downwardly as the arm 12 turns about its shaft 10. As soon as this forward 1n0vement begins the arm 78 passes out of engagement with the arm 75, therebv releasing the rockshaft and allowing the spring 81 to return the arm 58 and the pawl 61 to normal position, in which they are ready to again engage the ratchet wheel 55 upon the cutter being again elevated, the paWl 56 engaging the teeth of the ratchet and preventing the same from turning with the arm 58 as the same is moved into normal position. The balance wheel 32 may be provided with a handle 84, whereby 'the same can be turned in that direction in which the pinion moves freely, thereby rotating the cutter disk independently of its operating mechanism in order that the same may be cleaned or ground.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for 0bvious modifications will occur to a person skilled in the art. y
